Objective. Improvement of titanium filter efficiency
Our client, a manufacturer of specialized titanium filters, would like to improve the efficiency of their product. Its objective is to be able to offer greater porosity by reducing the diameter of the pores. In this way, they will be able to offer a new product since there is no manufacturer with those hole sizes.
The main requirement and challenge is that this new process minimizes the presence of oxides on the surface, so the holes will have to have a high quality finish.
Solution. Design and microperforation of the microholes
Our client had a porosity (microhole size) already defined as a target. As the first step of the project, we designed different geometries and hole distributions that could work well with this size of the microperforation.
At that point, we selected the laser that, with our experience, could give us the best results, taking into account 3 factors: the material of the filters, the thickness and the designs we had made. In our laser, we carried out a battery of real tests on the material. During the tests, it was verified which designs were viable for the following tests and which were not, and we did an optimization phase of the designs.
In this case, the validation tests consisted of measuring and recording the sizes through profilometry and confocal to verify that the dimensions were what we needed.
The project ended in this case with the delivery of the laser designs and parameters that we had used.
